The U.K.'s Beagle 2, which disappeared during a landing attempt in 2003, is clearly visible in new photos from the Mars Reconnaissance Orbiter currently at the Red Planet

The capsule was carried January 10 atop a Falcon 9 rocket that lifted off from Cape Canaveral. After launch the rocket came down as planned on a drone ship but hit a bit too hard

Research teams are failing to confirm plumes of water vapor reported a year ago to have been spewing about 200 kilometers into space from Europa's south pole

NASA's New Horizons probe is set to awaken from 99 days during which the spacecraft's electronics were largely unpowered. Observations at the dwarf planet start in January

A planet-forming disk around a million-year-old star has been imaged in unprecedented detail

Orbital Sciences’s Antares rocket burst into flames mere moments into its mission to send a cargo-carrying spacecraft to resupply the International Space Station. NASA reported no injuries to personnel

NASA's rovers and orbiters at Mars will witness a close encounter with a comet on October 19, an event that happens once every million years

The India Space Research Organization unveils its first pictures of the red planet

If all goes according to plan, the two companies will reduce or end NASA's dependence on Russia for its orbital taxi service

The satellite is destined for an orbit 438 miles above Earth and will use a spectrometer to measure CO2 concentrations in the air 24 times per second

What might be the effects if a large asteroid collided with Earth?

Kepler will rely on solar radiation pressure to balance its compromised pointing ability in order to make observations of targets in the plane of Earth's orbit

The European Space Agency's probe was successfully awoken from hibernation Monday and will begin preparations  to explore a comet

A mission consisting of a 180-day cruise to Mars, a 500-day stay on the Red Planet and a 180-day return flight to Earth could expose astronauts to a cumulative radiation dose of about 1.01 sieverts

With a density nearly identical to that of our planet, the exoplanet Kepler 78 b is just 20 percent wider and about 80 percent more massive than Earth

The team is currently making sure the hardware is safe and has until December 7 to get the probe off the ground, after which point it would have to wait 26 months for another favorable alignment of Earth and Mars

The robot will likely employ this "autonav" capability more and more as it continues the long trek toward the base of Mars' huge Mount Sharp

NASA announced that it will stand down on attempts to recover the exoplanet-hunting Kepler spacecraft, but might find other science uses for it

As the space agency's Curiosity rover celebrates one year on Mars, preparations are under way for the launch later this year of NASA's next Red Planet mission, called MAVEN

The damaged Kepler spacecraft's operating capability is much lower than expected, officials say

Even with the loss of its precision pointing ability, Kepler can still search for exoplanets, scientists say

Researchers have launched a Kickstarter campaign to fund the testing of miniaturized, high-efficiency propulsion technology

Upcoming cosmic alignments will give planet hunters an opportunity to intensify the search for potential exoplanets
